As for the curved hole processing, various developments are done in order to apply them on cooling holes of various dies or oil roads of oil pressure parts. But those most need complicated mechanism and the highly precise control in order to install a drive device to an electrode. A developed device is mechanism to process a curved hole by imitating shape processed already. Accordingly this device realizes processing of a curved hole with simple mechanism. As a result it can process a curved hole of various curvature and be able to confirm possibility of this system. And it is found that the control of liquid pressure and electrode turn can control curvature of a curved hole.
